Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 18.265   b = 30.69   c = 42.46 (Ångstroms)

α = 90.0   β = 90.0   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PROLSQ program. The R value is 0.18 for 9575 reflections in the resolution range 5.0 to 1.0 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
